Plant Identification -- Submerged Weeds -- Flat-Stemmed Pondweed |
FLAT-STEMMED PONDWEED (Potamogeton zosteriformis)
Treatment Tips: Where these plants grow in relatively deep water (6-8 feet), they can be treated more economically with granular herbicides.
Description: Stem large and conspicuously flattened. Leaves ribbon-like and extended upwards from flattened surface of stem.
Distribution: Common through out northern one-half of U.S. Plants seldom reach nuisance levels.
|
Recommended Control Method: Tank mix 1 part Cutrine-Plus to 2 parts Aquathol K. Apply at the rate of 1 gallon per acre-foot of water. Dilute to facilitate even distribution.
|
Maintenance Control Method: Add Aquashade at the rate of 1 quart per acre-foot of water to prevent initial growth or to retard regrowth of plants after chemical treatment.
|
Alternate Control Methods: Aquathol Granular: 27 to 81 pounds per acre-foot.
Aquathol K liquid: 0.6 to 1.9 gallons per acre-foot.
Cutrine-Plus/Reward: Tank mix in the ratio of 1:1. Apply 2 gallons per surface acre.
Fluridone: Various liquid and pelletized formulations (see label).
